KING CRAP ATTACK! Trailer

"Transgenic giant crabs attack the beaches of Trouville. The evil Raymond Santos, owner of a nearby processing plant, seeks to increase his company’s profitability by mucking about with the genetic structure of ordinary crabs, which proceed to do what all good self-respecting critters do in those circumstances: they grow to an enormous size and go on a rampage of destruction. They are uncontrollable. Basile Garaud, a member of the coastguard, conducts an investigation into the matter."
